Commidendrum rotundifolium, the bastard gumwood, is a species of tree endemic to the island of Saint Helena.

[2] In December 2009, Lourens Malan, a horticulturist working for the island's conservation department under the Critical Species Recovery Project, discovered a wild tree growing on a cliff.

A local team of botanists, conservationists and volunteers commenced an intensive programme of hand pollination and seed collection of the remaining cultivated tree, while protecting it from insects that may cross-pollinate with nearby false gumwoods.

Successful fertilisation will occur only if any grains of pollen happen to have mutations that will suppress the tree's mechanisms for preventing self-pollination.

With funding from DEFRA an intensive propagation and nursery programme has demonstrated that a low percentage (0.2%) of viable seed can be generated by this method, and as of October 2010, 250 seedlings have been grown for the recovery of the species.
